The Fluke Networks IntelliTone Pro probe detects IntelliTone digital signals, rejecting noise and false signals, to locate and trace data cabling on active networks. It detects 500 to 1200 Hz analog signals to isolate individual wire pairs and trace voice, audio, and video cabling on inactive networks. The probe detects signals at cable racks, in patch panels, and even behind walls, and identifies detected signals audibly and with eight LEDs that light successively as the signal strength increases for prompt isolation of a single cable within a bundle. A sync LED shows battery strength at power-up and confirms reception of IntelliTone signals. A cablemap function allows it to validate RJ11 and RJ45 connectors by testing continuity and finding short circuits, open circuits, and crossed-pair wiring faults on all four pairs of UTP and STP twisted pair cabling. RJ11 and RJ45 jacks plug into a port on the bottom of the probe. The probe turns off automatically after one hour of inactivity. Tone probes are used by network technicians to troubleshoot and maintain wires and cable in copper media networks.
